GRACE \"met its primary endpoint\", but \"the analysis was conducted in a highly enriched population\": of 102 patients with hypertension at baseline, 40 (39%) left during the open-label phase and only 46 (45%) entered the randomized-withdrawal phase, so the result \"likely overestimates the treatment effect\" in the intended population. GRADIENT, the parallel-group placebo-controlled trial, \"did not meet its primary efficacy endpoint\": 24-hour systolic pressure fell 5.8 mm Hg on relacorilant and 5 mm Hg on placebo (difference -0.85 mm Hg; 95% CI -6.7 to 4.9; p=0.77). Corcept's post hoc analysis in 33 patients with Cushing's syndrome (difference -10.4 mm Hg; nominal p=0.03) included only 8 of 16 and 13 of 17 patients; FDA's own analysis with a different method for missing data gave -4.9 mm Hg (95% CI -15.3 to 5.6; nominal p=0.36). The published GRACE paper shows how small the pivotal comparison was: 21 patients on relacorilant and 22 on placebo (odds ratio 0.17; 95% CI 0.04-0.77; p=0.022). FDA added that before submission it had told Corcept \"on several occasions\" of its concerns and \"to expect significant review issues\".",

FDA also reviewed the exploratory findings on body weight and blood glucose and was \"not persuaded that such benefits were observed\". The resubmission of 17 June 2026, in Corcept's words, \"includes additional analyses of data included in the original NDA submission\" and rests on the same studies: GRACE, GRADIENT, the long-term extension study and earlier trials. ClinicalTrials.gov lists no new controlled trial of relacorilant in Cushing's syndrome. What the analyses are, and what they show, is not public. Efficacy problems are historically the hardest to cure: in FDA's own study of new molecular entities first submitted in 2000-2012, efficacy deficiencies were present in 61 of the 80 applications never approved, against 28 of the 71 approved after resubmission.

      "evidence": "After its safety review FDA \"concluded that relacorilant is associated with drug induced liver injury (DILI)\". Among 303 people who received the drug, four cases were assessed as probable DILI; one patient's ALT reached 1952 U/L, \"more than 50 times the upper limit of normal\". None met Hy's law criteria. FDA wrote that more cases may occur with longer exposure after approval and that \"we cannot conclude that relacorilant has a favorable benefit risk assessment for the proposed indication\". It also recommended a proposal for \"DILI risk mitigation strategies including appropriate labeling warnings, routine monitoring requirements, enhanced pharmacovigilance, and post-market evaluation\", which suggests the risk could be handled in labeling once benefit is shown. Corcept disputes the finding: on 24 February 2026 its chief development officer said the company's assessment, confirmed by an external independent safety committee, was that the endocrinology programme had no cases of drug-induced liver injury. The label of Lifyorli, approved in March 2026 at 150 mg on three days around each chemotherapy infusion, has no liver-injury warning; treatment of Cushing's syndrome is daily and long-term (100 to 400 mg a day in GRACE).",

In GRADIENT (137 patients, double-blind, 22 weeks) the secondary endpoints favoured relacorilant with nominal significance, as reported by Corcept: body weight -3.9 kg against placebo (p=0.0001), fasting glucose -22.2 mg/dL (p=0.002) and HbA1c -0.3 percentage points (p=0.019). The letter itself says \"relacorilant may have benefit for the broader indication\", and since the resubmission Corcept describes the application as for \"patients with Cushing's syndrome\" where in December 2025 it said \"hypertension secondary to hypercortisolism\"; the indication actually proposed is not public. Relacorilant blocks the same receptor as mifepristone (Korlym), marketed for Cushing's syndrome since 2012, and has orphan designation.

        "evidence": "FDA 的完全回应函（CRL）（生效日期 2025 年 12 月 30 日；更正版签发于 2026 年 1 月 28 日）写明，现有证据不足以证明 relacorilant 对拟定适应症有效。GRACE 达到了主要终点，但函中指出分析是在高度富集的人群中做的：基线有高血压的 102 名患者中，40 名（39%）在开放标签阶段退出，只有 46 名（45%）进入随机撤药阶段，因此结果很可能高估了药物在目标人群中的疗效。平行分组、安慰剂对照的 GRADIENT 未达主要疗效终点：24 小时收缩压在 relacorilant 组下降 5.8 mm Hg，安慰剂组下降 5 mm Hg（组间差 -0.85 mm Hg；95% CI -6.7 至 4.9；p=0.77）。Corcept 在 33 名库欣综合征患者中做的事后分析（组间差 -10.4 mm Hg；名义 p=0.03）只纳入了 16 名中的 8 名和 17 名中的 13 名；FDA 换用另一种缺失数据处理方法自行分析，结果为 -4.9 mm Hg（95% CI -15.3 至 5.6；名义 p=0.36）。已发表的 GRACE 论文显示，关键比较的规模很小：relacorilant 组 21 人，安慰剂组 22 人（比值比 0.17；95% CI 0.04-0.77；p=0.022）。FDA 还写道，申报前已多次向 Corcept 说明顾虑，并提醒它若提交申请，要有遇到重大审评问题的准备。"
